Transfemoral versus trans-subclavian access in transcatheter aortic valve implantation using self-expandable valve: A propensity-matched comparison.

Background: Transcatheter aortic valve implantation is unfeasible for 10-15% of patients using the conventional transfemoral approach. Other alternative approaches, such as the subclavian approach, have emerged, with no clear recommendation indicating the superiority of one technique over another.

Aim: To compare the 1-month mortality and postprocedural outcomes of patients undergoing transcatheter aortic valve implantation using a self-expandable valve via transfemoral and subclavian access.

Emergency bailout surgery saves lives in high-risk patients with complications after TAVR.

Introduction: With the expansion of the indication for transcatheter aortic valve implantation (TAVR), the value of access to on-site emergency heart surgery at performing centers needs to be assessed.

Aims: To evaluate postoperative mortality after surgical rescue post-TAVR, in a population at high surgical risk.

Methods: Retrospective analysis of a cohort of patients included in the France-TAVI registry who had undergone TAVR with the latest generation valves between January 2017 and February 2020.

How to use the aortic valve calcium score to improve the results of transcatheter aortic valve implantation with a self-expanding prosthesis.

Background: In recent years, transcatheter aortic valve implantation (TAVI) without predilation (direct TAVI) has become the preferred method for implanting TAVI prostheses. Appropriate patient selection is important to avoid suboptimal outcomes and associated complications.

Aim: To evaluate whether aortic valve calcification measured with computed tomography predicts suboptimal results from direct TAVI with a self-expanding prosthesis.

Evolution of chronic kidney disease after surgical aortic valve replacement or transcatheter aortic valve implantation.

Background: Immediate improvement in kidney function has been reported after surgical aortic valve replacement or transcatheter aortic valve implantation. Long-term data, however, are not available.

Aim: To assess the evolution of kidney function in chronic kidney disease stage 3b-5, 1 year after surgical aortic valve replacement or transcatheter aortic valve implantation.

Effectiveness of anticoagulant therapy in the treatment of post-TAVI bioprosthetic thrombosis.

Bioprosthetic thromboses are rarely reported in post-transcatheter aortic valve implantation (TAVI). We describe herein the case of bioprosthetic valve thrombosis in an 82-year-old patient which resolved completely after anticoagulant therapy.
